PRINEVILLE, OR -- Firefighters worked through the weekend to strengthen containment lines around a wildfire near Elkhorn campground in the Maury Mountains. The 1700-acre fire began as a prescribed burn to improve range and forest health within a 333-acre unit of the Ochoco National Forest. Unexpected wind pushed the fire across containment lines on Thursday, creating the wildfire. A temporary closure is in effect for hunters and other visitors in the area.
